Abstract

I discuss accurate theoretical predictions for masses of baryons containing the b quark. I point out an approximate effective supersymmetry between heavy quark baryons and mesons and provide predictions for the magnetic moments of Λ_c and Λ_b. Proper treatment of the color-magnetic hyperfine interaction in QCD is crucial for obtaining these results. Closely related methods are then applied to doubly-heavy hadrons: the recently observed exotic Q¯Qq¯q mesons and QQq baryons. Predictions are given for the masses and decay modes of additional Q¯Qq¯q mesons and of QQq baryons: Ξ_cc(ccq), Ξ_bb(bbq) and Ξ_bc(bcq), which might soon be seen experimentally, as indicated by the large number of Bc mesons observed by LHCb.
